<!--!introduction!--> The Ross Ice Shelf (RIS) floats over the southern sector of the Ross Sea creating beneath a crucial area for ocean-ice interactions, known as the cavity. This area is characterized by the formation of Ice Shelf Water (ISW) as well as the intrusion of warm water, which is the main driver of basal melting and ice shelf calving. Ocean-driven basal melting and calving are the predominant causes of ice-shelf buttressing losses and the ice discharge that directly affects the global sea level. While the RIS is not considered to be under threat from the on-shelf intrusion of warm Circumpolar Deep Water (CDW), dense High Salinity Shelf Water (HSSW) and seasonally warmed Antarctic Surface Water (AASW) are expected to cause significant basal melting. The RIS northwest sector, which is directly exposed to solar-heated AASW, sees melt rates that nearly triple during the summer months. In this work, we present unprecedented thermohaline observations from Argo floats close to the north-western ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
